You must make two changes in the "Editor - JoomlaFCK" plugin...
1. From your Joomla Control Panel access Extentions>Plugins>Editor - JoomlaCK
2. Under "Parameters" disable JoomlaFCK from using the default by changing the option in "Use Editor CSS Classes"; set to NO
3. You must enter the path to the Shape5 CSS file "template_css.css" into the "Use Custom CSS Classes". Should look like "/templates/sportopolis/css/template_css.css"
That should about do it.
